Abstract (en)
[origin: EP3570454A1] A system (520) for simultaneously driving a plurality of antennas (106, 108) for transmission of an electromagnetic wave includes a first terminal, a second terminal, a first driver (508) coupled to the first terminal, and a second driver (510) coupled to the second terminal. The system includes a circuit (502) configured to generate an indication of a phase difference between a first current through the first terminal and a second current through the second terminal. The system includes a control circuit (504) configured to enable the first driver and the second driver to concurrently drive a first signal through the first terminal and a second signal through the second terminal, respectively, and configured to adjust a delay (1002, 1102) between the first signal and the second signal based on the indication of the phase difference and a predetermined target phase difference.
